Friends, family and Hollywood’s elite are en route to Kim Kardashian and Kris Humphries’ wedding, and Twitter has become something of an online guestbook for everyone who’s making their way to the massive celebration.

Maria Menounos posted a photo showing her looking absolutely stunning — and abiding by the black-or-white dress code — in a form-fitting white gown. Meantime, everyone heading to the wedding seemed to want to share their emotions via Twitter on Saturday.

Kendall Jenner sent a special message to her big sis, saying: “”BIG DAY! My sissy is getting married today!!! So happy for you @kimkardashian! Love youuuu””

Kim’s friends also chimed in, as pal Brittny Gastineau said via Twitter: “”Only a few hours to go till @KimKardashian gets married!!! So excited for her!!! Ahhhhhh” while Jonathan Cheban gushed “”15 min nap…then almost time to get ready for my best freinds wedding! So happy for her!!!”

Lala Vasquez, one of Kim’s very best friends, could hardly contain her excitement, saying: “Butterflies in my stomach for @KimKardashian & @Krishumphries…beyond excited for today! the Anthonys are on our way! Love is in the Air!” while her other BFF Ciara said: “”2Day is Princess Kimmies Day! Ow! So excited and happy for her! Will be a beautiful day indeed!”

Meanwhile, Lara Spencer ran into some wardrobe issues and had to use a little creativity. She wrote: “Asked Hubby to zip up my dress for @KimKardashian’s wedding. Muscles Broke it! Plan b dress–never hemmed! Plan C? Cocktail and wing it.
